I don't think so. The best way to check it is by eye. I'd tell you to  
read the documentation, if it was online any more. Basically, you  
just have to play the video back and do a frame-by-frame advancement  
viewing. Pause, hit the [.] (period) button to advance by a couple  
frames.

Sometimes yes, sometimes no. If it deinterlaces a progressive source,  
the results will look... odd.
